I've received some insulting low ball offers and I've come close to sending a very sarcastic reply but I try my best not to do that.
A few years ago, a guy gave me a sob story about how he really wanted this particular model bass that I was selling and that he had saved for so long and all he could come up with was $X and wanted me to give him a deal. I lowered my price for him and then a week later he had the bass up for sale in the classifieds at more than $400 more than I was originally asking.Live and learn.
I am too easy to rip people apart for insulting lowballs.
Note to everyone - anyone who gives a sob story of any kind is a tool you should avoid.
The most common ones:
"I want to get this for my son but I'm broke"
"_____ is in the hospital, I am broke"
"I have (insert disability), give me a deal"
"I am a military vet, give me a deal"
Live and learn.
